Be careful of wraparound Rx sunglasses

July 29th, 2010

In order to achieve a maximum degree of eye coverage, sunwear manufacturers typically take a wraparound lens or frame design. In this case, the lenses will be made with extreme curves, especially at the edge. This is really a favorable design because related users can protect their eyes as much as possible. Each pair of these quality sunglasses can shield nearly the whole lens socket from all angles. Today, this wraparound design using extremely curved lenses are taken by almost all notable sunwear brands like Native, Ray Ban, Smith, Bolle and Oakley, just to name a few. What’s more, some people may have heard of wraparound Rx sunglasses. This term refers to wraparound sunglasses that have specific prescriptions for vision correction. From another perspective, most people would suppose that they are only the natural and typical form of prescription sunglasses. This is only partially true. Customers who are interested in these products should take additional consideration.

It is true that there is an increasingly number of customers who appreciate greatly the benefits brought by prescription sunglasses or tinted eyeglasses. UV protection and vision correction are combined within a single eyewear. For folks regularly participating in outdoor activities with poor eyesight, it is hard to point out that which of the above functions provided by Rx sunwear is more important. UV protective lenses are quite essential to fight against hazardous ultraviolet rays. In this consideration, a wraparound lens design discussed before should be the first choice. However, the problem is that this wraparound design involves inevitably extreme lens curves, which in turn typically distort the wearer’s vision. With this explanation, it is understandable that some people consider wraparound Rx sunglasses as a product of dilemma.

The availability of these sunglasses is quite limited because of this confliction between the wraparound design and corrective vision distortion. The currently situation in the market of wraparound Rx sunglasses is that only a few manufacturers provide these products yet with less extreme curves. What does this mean? When certain lens powers should be successfully fitted into sunwear lenses, it is inevitable to compromise in different degrees the wraparound curves. Moreover, only a limited prescription range has been typically available.

Additional benefits of progressive sunglasses

June 17th, 2010

For some groups of people, both UV protection and vision correction are necessary when they are in an outdoor environment. While eye protection against fierce and harmful sunlight is critical for all people living on earth, a lot of individuals are forced to resort to vision-aid devices by conditions like nearsightedness, farsightedness, astigmatism and presbyopia. Sunglasses and clip on shades may have been quite common products among the public. But prescription sunglasses may be less frequently heard by ordinary people who are not experienced about the sunwear and eyeglass industries. And progressive sunglasses may be known by significantly fewer individuals. In fact, these different forms of sunwear suggest a rapid progress in this industry. Clip on sunshades are the simplest form that they can be clipped onto regular prescription eyeglasses. Prescription sunglasses and progressive sunwear offer further benefits in terms of vision aid.

In a time when prescription and progressive sunwear were unavailable, clip ons and magnetic attached sunglass lenses were widely used by people who used regular prescription eyeglasses. The problem is that this requires sometimes temporary clipping and removing a clip-on, which can be inconvenient and even dangerous. For example, searching in vain for those clip-ons during driving with the presence of fierce sunshine may involve dangerous factors. For people who wear prescription contact lenses, using an additional pair of sunglasses for UV protection may not be a good idea, especially in certain outdoor environments like on the beach or in a swimming pool. Contact lenses can make the eyes itchy and watery or even cause serious eye infections in these activities. Prescription sunglasses are a good product that combines separate functions. And progressive sunglasses come in a similar principle to single vision prescription sunglasses.

As the name indicates, progressive sunwear also deals with both UV protection and vision aid within a sole pair. Thus they have the same advantages that are boasted by regular prescription sunwear. The additional benefits of advantages of progressive sunglasses lie in their multifocal property. Progressive lenses used by these devices are the essential part. Like regular progressive reading glasses without UV protection, progressive sunwear can offer clear vision at all distances.

However, flat surfaces like smooth water can separate sunlight into two polarized components which will then be reflected and transmitted in different amounts. In detail, more horizontal components will be reflected than vertical components. And an excessive amount of horizontally reflected light is the major source of glare experienced by people in such an environment. Polarized sunglasses take use of lenses that have polarized filters with the transmission axis oriented vertically, thus they can filter out unwanted horizontal light reflected by smooth surfaces. This principle explains why fishermen, bikers, golfers, joggers and skiers will receive little glare when they put on their polarized sunwear.

Polarized sunglasses are now provided by nearly all notable sunwear brands like Prada, Versace, Dior, Ray Ban and so forth. This technology has been a basic requirement or capability which can be taken to evaluate an eyewear brand. Sunglasses made of polarized lenses all come in shades from light gray to very dark, or photochromic. In other words, polarized sunglass lenses can not be crystal clear.

Some of these outdoor activities require a clear near vision. For instance, some people may try to read a newspaper on the shore. In some cases, hunting requires a person to read a map in a forest.
